Here they are 10 days in and tensions are high in almost every group.

El Bosque
Shane is clashing with his teammates still and Alana and Danielle are pushing him away. While he's hunting they're conserving their energy and both feel they are doing things the right way. After getting extremely hungry he chops down a tree for the fruit and they laugh at him. While his approach may seem off, Alana's attitude is off putting. When Shane leaves for most of the day the girls start talking about how they may need him there to fend off an animal, when only a few days before they were asking him to leave saying they didn't need him. Can't have it both ways, ladies. So Shane has decided to build another, secret shelter a quarter of a mile away from the camp. This brings their PSR from 7.3 to 6.9. Once Shane's "lodge" is complete he breaks the news to the others about his departure.

The all female group is thriving but in need of calories. And maybe in need of a group therapist. Since Laura and Eva have known each other for so long they do everything together and Dani feels left out. If they replenish their energy their hormonal levels should return to normal. While off to hunt Dani smells smoke, leading her straight to Cano Verde. Instead of walking right into their camp she sneakily hunts them, looking like the hamburglar to their nuts and fruit. Once caught, they embrace her... showing her their "swimming pool" and sharing their food. They quickly realize she carries a big stick, or knife. She welcomes them to it during her visit. Looks like this could be a great new team. Back at her original camp Laura and Eva feel Dani is a liability. Without teamwork their PSR drops from 8.6 to 7.7. When Dani re-earns the others' trust they group hunt at night in cayman infested water. Coming up with nothing, the girls believe a trip to Cano Verde is in order.

Cano Verde
Honora has deliberately sabotaged her teammates but isn't backing down nor apologizing. Chris and Luke are faced with facing the remainder of the 40 days without tools. There's only one survival item left. But at least she's tapping out so they don't have her, either. I don't think she'll be missed. She feels like she's being forced out by her teammates but I suspect that the audience feels differently. Now that she's gone, their task is to find their sunken tools. First treasure found is their water bottle, next is the knife. Now Chris needs to replenish his calories he spent snorkeling. After meeting Dani upon their camp, they are left with the discussion of wether or not they'll allow more people into the group. "It's a game changer." They may be willing to take Dani, but not the rest of her group. Maybe they should follow Dani back to her camp and sneakily find out who the other two are. With Honora gone their PSR score raises from 6.6 to 7.0.

EJ and Jeff are the only guys of this group left. At the moment they are extremely hungry and losing weight quickly. As luck would have it, they happen upon a turtle which will provide them with about 5,000 calories. It kind of looks like the turtle Shane had to unwillingly say goodbye to earlier in the challenge in El Bosque. Before cooking the turtle they build a pen to keep him in so he doesn't get away. Welp, that didn't work. Haven't the read The Tortoise and the Hare? That little guy worked smart. Now they feel moving on to find more resources would be their best strategy. After gaining then losing a meal their PSR is unchanged at 7.1.
